Shoe Peeling Strength Tester
Category：Footwear Strength Tester
Introduction
The Shoe Peeling Strength Tester is designed to evaluate the adhesive bond strength between the shoe upper and sole. By simulating the peeling process under controlled conditions, the tester measures the force required to separate the sole from the upper, providing quantitative data on the bonding quality and durability of finished footwear.
Applications
(1)Testing the peeling strength of athletic shoes, safety shoes, casual shoes, and leather footwear.
(2)Quality control in footwear manufacturing to ensure reliable sole-to-upper adhesion.
(3)Research and development of adhesives and bonding processes for shoe production.
(4)Evaluation of different sole materials, including rubber, EVA, PU, and leather.
(5)Assessment of complete shoes under simulated real-world peeling conditions.
(6)Verification of compliance with industry standards for whole shoe bonding performance.
(7)Comparative testing of different shoe construction methods (cemented, vulcanized, or stitched).
Standards
(1)GB/T 15107-2013 — Footwear — Determination of Bonding Strength Between Upper and Sole
(2)GB/T 3903.3-2011 — Leather Footwear — Part 3: Adhesion Strength of Upper to Sole
(3)BS 20344 — Test Methods for Footwear — Determination of Bond Strength
(4)QB/T 4329-2012 — Footwear Industry Standard for Peeling Strength
(5)QB/T 1002-2015.6.5 — Rubber and Plastic Footwear Adhesion Test

Maintenance Information
(1)Keep the peeling knife and clamping system clean and free of adhesive residues.
(2)Regularly inspect the force sensor and dial gauge for accuracy.
(3)Lubricate moving components to maintain smooth operation.
(4)Check and tighten fixtures and bolts periodically.
(5)Store the tester in a dry, stable environment to prevent corrosion and mechanical wear.
